Abstract

An annunciator for training individuals in toilet etiquette and sanitation. The annunciator has a small housing that hangs on the side of the toilet tank, is incorporated into the seat of the toilet or hangs from the flush handle of the toilet. The housing is preferably plastic and can be animal shaped, for example, like a frog. A sound module, batteries, internal sensors, controller and speaker are mounted in the housing and the controller is connected to the external sensors by electrical wires. A small light such as an LED can be included to indicate that the unit is working. The sensors detect a person near the toilet, the position of the toilet seat (lowered or raised), a person sitting on the seat, and operation of the flush handle. The controller decides what messages to play based on the sensed conditions. Additionally, the housing may contain a small separate tape player for music or prerecorded humorous sounds. The tape player is controlled by the annunciator to coordinate with any played messages. An on/off switch and volume control are also provided.

       4. The annunciator according to claim 1, wherein the toilet further includes a toilet tank with a side, and wherein: said annunciator further comprises a housing supported on the side of the toilet tank;   said battery, said motion detector, said audio storage device, said speaker, said audio amplifier and said controller are all mounted in said housing;   said flush handle sensor is electrically connected to said controller by a first electrical cable; and   said seat up/down sensor and said seat occupied sensor is electrically connected to said controller by a second electrical cable.   
     
     
       5. The annunciator according to claim 1, wherein the toilet further includes a toilet tank with a front and a flush handle shaft operatively connecting the flush handle to the toilet, and wherein: said annunciator further comprises a housing supported by the flush handle shaft on the front of the toilet tank;   said battery, said motion detector, said flush handle sensor, said seat up/down sensor, said audio storage device, said speaker, said audio amplifier and said controller are all mounted in said housing; and   said seat occupied sensor is electrically connected to said controller by an electrical cable.   
     
     
       6. The annunciator according to claim 1, wherein: said annunciator further comprises a housing built into the toilet seat;   said battery, said motion detector, said seat up/down sensor, said seat occupied sensor, said audio storage device, said speaker, said audio amplifier and said controller are all mounted in said housing; and   said flush handle sensor is electrically connected to said controller by an electrical cable.   
     
     
       7. The annunciator according to claim 1, wherein: when the motion detector provides a signal that indicates a person is within the predetermined distance;   when the seat up/down sensor provides a signal indicating the seat is in the lowered position;   when the seat occupied sensor provides a signal indicating that the seat is not occupied; and   when the flush handle sensor provides a signal indicating that the handle is not being operated; then one of the at least one audio message selected and played is of a humorous nature; or   no message is selected and played.     
     
     
       8. The annunciator according to claim 1, wherein: when the motion detector provides a signal that indicates a person is within the predetermined distance;   when the seat up/down sensor provides a signal indicating the seat is in the raised position;   when the seat occupied sensor provides a signal indicating that the seat is not occupied; and   when the flush handle sensor provides a signal indicating that the handle is not being operated; then the at least one audio message selected and played is of a warning nature and states that the seat is in the raised position.     
     
     
       9.
